Genes affected

MTF2 (HGNC:29535): (metal response element binding transcription factor 2) Enables methylated histone binding activity and transcription corepressor binding activity. Predicted to be involved in several processes, including regulation of histone H3-K27 methylation; regulation of transcription by RNA polymerase II; and segment specification. Predicted to act upstream of or within cellular response to leukemia inhibitory factor. Located in cytoplasm; focal adhesion; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
